(Chaim) Herman Müntz (28 August 1884, in Łódź – 17 April 1956, in Sweden), Polish-German mathematician, now remembered for the Müntz approximation theorem. He was active in Berlin and Munich and worked closely with Einstein in 1927. In 1929 he was appointed professor at the University of Leningrad where he worked until he was expelled as a German citizen in 1937 when he moved to Sweden where he lived for the rest of his life. He collaborated closely with Einstein in the years following 1927, and his help is acknowledged in a number of papers.
